Challenging? :p

no too hard

Very good.

Not even hard!

I tried to take the rook on h8 and when it said that was wrong I said "But ... it's free!:("

1st

so easy

easy...

basics.....how about some thinkers

Last!

Simple.

I agree! so what if you are first, no one cares.

This was a nice one. Beautiful Queen sac!!!

It's almost always a Queen sac.

life and everything in it needs no explaination. hmmz

Challenging?

Very easy!!!!

Correct me if im wroung but if rxd5;bxd5,Qc7#That could work also if black doesn't prevent it.

easy!

 First!

opps said them :)

interesting to sacrifice the queen, thanks for the tip

Alternative: 1 Rxd5 Bxd5; 2 Qc7#.

If the bishop doesn't capture, then 2 Rd8# anyway.

Once the knight is gone, there is no way to guard both c7 and d8.
